The stator has an opening adapted to surround a first portion of a rotatable shaft, a transmit region, and a receive region. The rotor has an opening adapted to surround a second portion of the rotatable shaft, an annular conductive region, and at least one conductor electrically coupled with the annular conductive region. The controller has an input coupled to the receive region and has an output coupled to the transmit region. The controller is configured to transmit a first signal on the output of the controller and to the transmit region of the stator, receive a second signal on the input of the controller and from the receive region of the stator, and determine, based on the second signal, a proximity of the at least one conductor to the receive region.

摘要： An occupant or object sensing system in a vehicle includes electrical circuits for capacitive sensing and corresponding circuits shielding the sensing system from interference. A sensing circuit and a shielding circuit may be printed by screen printing with conductive ink on opposite sides of a non-conductive substrate. The substrate is a plastic film or other fabric that has an elastic memory structure that is resilient to stretching. The conductive inks used to print circuits onto the substrate have a similar resilience to stretching such that the substrate and the circuits thereon can be subject to deforming forces without breaking the printed circuits. The substrate may be covered with a carbon polymer layer to provide alternative conductive paths that enable fast recovery for conduction in the presence of any break in the printed conductive traces on the substrate.

摘要： The present invention is directed to a CV conversion amplifier which is small in current consumption and capable of securing a sufficient capacitance-voltage conversion gain and a sufficient amplitude range of an output voltage and a capacitive sensor using the same which is low power consumption, low in noise, and wide in an input signal allowable range. A capacitive sensor includes first and second detection capacitors, a CV conversion circuit includes first and second feedback capacitors and obtains a voltage based on capacitance values of the first and second feedback capacitors, an AD converter performs analog digital conversion on an input voltage and obtains a digital signal, a digital control unit receives the digital signal as an input, and first and second digitally controlled variable capacitors have capacitance values that are controlled by the digital control unit.

摘要： Electrostatic capacitance can be measured with high directivity in a specific direction. A sensor chip that measures the electrostatic capacitance includes a first electrode, a second electrode and a third electrode. The first electrode has a first portion. The second electrode has a second portion extended on the first portion of the first electrode, and is insulated from the first electrode within the sensor chip. The third electrode has a front face extended in a direction which intersects with the first portion of the first electrode and the second portion of the second electrode, and is provided on the first portion and the second portion. The third electrode is insulated from the first electrode and the second electrode within the sensor chip. No portion is extended from the first electrode to be positioned above the first portion.

摘要： The present invention concerns an electronic measurement circuit for measuring a physical parameter. The circuit comprises: a measurement sensor comprising two differential mounted capacitors each comprising a fixed electrode, and a common electrode, common to the two capacitors which is arranged to be movable relative to each fixed electrode of the two capacitors in order to alter the capacitive value of each capacitor when the physical parameter is measured. The circuit further comprises a first integrator unit connected to the common electrode for integrating charge received from the measurement sensor, and comprising two integrators arranged to be connected alternately to the common electrode; a second integrator unit connected to the first integrator unit for integrating charge received from the first integrator unit; a comparator for comparing analogue output values from the second integrator unit; a switch circuit connected to the measurement sensor for switching different voltage values across the two capacitors; and a feedback circuit for feeding a digital output signal of the comparator to the switch circuit for controlling the operation of the switch circuit.

摘要： A technique for operating a capacitive sensor array is described. The technique includes measuring a first capacitance of a first set of electrodes at a first time, measuring a second capacitance of a second set of electrodes at a second time, and calculating a position of a conductive object based on a relative magnitude of the first capacitance and the second capacitance. The first set and the second set includes at least one electrode in common and at least one electrode that is not in common.
